Lower Part of Earth’s Atmosphere is Warming, Data Review Concludes

By Guest PostNovember 16, 2010Environmentatmosphere, climate models, earth, lower part, north carolina state university, troposphere, warming

The troposphere, the lower part of the atmosphere closest to the Earth, is warming in ways that are broadly consistent with both theoretical expectations and climate models, according to a new scientific study from the National Oceanic and Atmospheric Administration (NOAA) and the NOAA-North Carolina State University Cooperative Institute for Climate and Satellites (CICS).

Since the development of the first climate models in the 1960s, the troposphere has been projected to warm along with the earth’s surface because of the increasing amounts of greenhouse gases in the atmosphere. This expectation has not significantly changed even with major advances in climate models. (more…)

Better Weather: Water-vapor Profiling System Could Result in More Accurate, Less Costly Forecasting

Researchers at the Georgia Institute of Technology and Bennett Aerospace are leveraging light detection and ranging (lidar) technology to develop a ground-based system that will automatically measure water vapor in the atmosphere. Known as”WaV-Pro^TM,” for Water Vapor Profiler, the system aims to provide more frequent data collection that could dramatically improve weather forecasting.

Initial work on the project began in mid-2009, when Bennett Aerospace, in collaboration with the Georgia Tech Research Institute (GTRI), won a Phase I Small Business Innovation Research grant from the National Oceanic and Atmospheric Administration (NOAA) to develop design requirements for the system. Recently, the researchers won a Phase II grant to build and test critical components needed for a final operating prototype of WaV-Pro. (more…)

The Arctic sea ice cover appears to have reached its minimum extent for the year, the third-lowest recorded since satellites began measuring sea ice extent in 1979, according to the University of Colorado at Boulder’s National Snow and Ice Data Center.
